To make a long story short my bf's parents are moving and there cat just had kittens and didnt' want to take them 4 hours away so we picked them up and brought them to our house but we we went to open the door the mother cat ran away with a kitten in her mouth.. now we have 2 kittens left with no mother cat.. the kittens are 2 days old and we went to the vet and got mammalac to give to them to drink but they wont' drink it...... I could use some help in figuring out how to feed them.
